Abstract

A display device includes: a display unit including a plurality of light emitting areas, a plurality of thin film transistors, and organic light emitting elements; an input sensing unit including a plurality of sensing electrodes and disposed on the display unit, wherein the plurality of sensing electrodes includes a plurality of openings; and an anti-reflection member. Each of the organic light emitting elements includes: a first electrode disposed above a first thin film transistor of the thin film transistors and connected to the first thin film transistor through a contact hole; a light emitting layer disposed on the first electrode and overlapping a first light emitting area of the light entitling areas; and a second electrode. Each of the light emitting areas is exposed by a corresponding opening of the plurality of openings, and the plurality of sensing electrodes overlaps with the contact holes.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A display device comprising:
 a display unit including a plurality of light emitting areas; and an input sensing unit including a plurality of sensing electrodes disposed on the display unit, wherein each of the plurality of sensing electrodes comprises: 
 a plurality of mesh lines; and 
 a plurality of cover electrodes, 
 wherein the mesh lines comprise: 
 a plurality of first mesh lines; and 
 a plurality of second mesh lines intersecting the first mesh lines, wherein areas where a first mesh line of the plurality of first mesh lines intersects a second mesh line of the plurality of second mesh lines are intersection areas, 
 wherein each of the plurality of cover electrodes is disposed on a respective intersection area, 
 wherein a width of a first portion of each of the first and second mesh lines in the intersection area is greater than a width of a second portion of each of the first and second mesh lines adjacent to the intersection area. 
 
     
     
       2. The display device of  claim 1 , wherein the plurality of cover electrodes covers each intersection area. 
     
     
       3. The display device of  claim 2 , wherein each of the cover electrodes has a circular shape. 
     
     
       4. The display device of  claim 1 , wherein the plurality of sensing electrodes comprises:
 a plurality of first sensor patterns arranged in a first direction; 
 first connection patterns, wherein each of the first connection patterns is disposed between the first sensor patterns adjacent to each other and connects the first sensor patterns to each other; 
 a plurality of second sensor patterns arranged in a second direction intersecting the first direction; and 
 second connection patterns, wherein each of the second connection patterns is disposed between the second sensor patterns adjacent to each other and connects the second sensor patterns to each other, 
 wherein each of the first and second sensor patterns comprises the plurality of mesh lines. 
 
     
     
       5. The display device of  claim 1 , wherein the display unit comprises:
 a plurality of organic light emitting elements; and 
 an encapsulation layer disposed on the plurality of organic light emitting elements and covers the plurality of organic light emitting elements, 
 wherein the input sensing unit directly disposed on the encapsulation layer. 
 
     
     
       6. The display device of  claim 5 , wherein the input sensing unit further comprises an insulating layer on which the plurality of sensing electrodes are disposed, and
 wherein the insulating layer directly disposed on the encapsulation layer. 
 
     
     
       7. The display device of  claim 5 , wherein a plurality of openings are formed by the first and second mesh lines, and
 each of the light emitting areas is exposed by a corresponding opening of the plurality of openings of the plurality of sensing electrodes. 
 
     
     
       8. The display device of  claim 5 , wherein the display unit further comprises a plurality of thin film transistors,
 each of the plurality of organic light emitting elements comprises a first electrode connected to each of the plurality of thin film transistors through a contact hole, and 
 the intersection area overlaps with the contact hole. 
 
     
     
       9. The display device of  claim 8 , wherein an area of the intersection area is equal to or greater than an area of the contact hole.
